WAGON-BOLSTER SPRING.

SPECIFICATION forming part of Letters Patent No. 394,935, dated December 18, 1888.

Application filed September 29, 1888. Serial No. 286,796. (No model.)

It all who/1t it may concern:

Be it known that I, LUTHER PULLIAM, of Ironton, Missouri, have made a new and useful Improvement .in \Vagon-l-Eolster Springs,

5 substantially as is hereinafter described and claimed, aided by the annexed drawings, making part of this specification, in which Figure l is a side elevation of a wagonbolster having the improved device applied thereto; Fig. 2, an end elevation of the same; Fig. 3, a section on the line 3 3 of Fig. 2, and Fig. I a section on the line I t of Fig. 1.

The same letters of reference denote the same parts.

I 5 Thebolster A and stamlardsll 3 are of the usual construction, saving as it maybe modified or supplemented by the improvement in question.

0 represents the wagon-bed, which also is of the ordinary form, with the exception of the appliances 1) used to connect the bed with the sprin At each end thereot' the bolster is supplied with a pair of arms, E E, whose timetion it is to uphold a pair of springs, from which in turn the wagon-bed. is suspended. The arms rise from the bolster against and respectively upon opposite sides of the standard. At the lower end thereot the arms 0 are preti'crably not connected with the bolster directly in. the vicinity of the stai'idard, but at a point nearer to the center of the bolster, thereby to enable the weight of the wagonbed to be sustained more especially by the cen- 5 tral portion of the bolster. To this end the arm is made to consist of an upright portion, e, and a horizontal portion, 0, the upright portion being made to rise from the bolster in line with the standard, and the horizontal 4o portion being extended along the side a of the bolster, and being fastened thereto at the inner end, 6 of the arm. The two arms E E are conveniently attached to the bolster by means of the bolts e e.

A saddleshaped metallic piece, 6, is pref.-

erably placed upon the bolster at the point where the arms E E are attached, and the bolts e 6 pass not only through the arms E E and bolster, but also through the sides of the piece c, as shown. The sides may have at the lower end thereof a flange, e, which may aid in supporting the arms E E. The arm portions 6 e are, and preferably by means of the band I tied to the standard, partly to better hold the arms in place and partly to brace the standard. The band is upheld in place by reason of the tapering form of the standard. Atits upper end each arm portion 6 is shaped substantially as shown, to enable a spring, G, to be attached thereto, sul'istan- 6o t-ially as shown.

The spring hangs alongside the arm portion 6, and at its lower end the spring is, by means of the appliance I), connected with the wagonbed. The appliance D is in practice a strap secured at its end (I to the wagon-bed, and at its cn d 1' made hook-shaped orot some equivalent shape to enable it to be connected with and disconnected from the spring. The straps D I) for each pair of springs project from the wagon-bed to come respectively against or past the arm portions (2 e, as shown, and they thus also serve as a means for holding the wagon-bed longitudinally from slipping. The springs are an assistance in this respect. As a modification, the straps I) l) might be attached to a board extending across "beneath and thereby supporting the wagon bed. \Yhen it is not desired to use the springs, the wagon-bed can. be detached therefrom, and when it is desired to support a comparatively light load one of each pair of springs can be disconnected from the wagon-bed.

It will. be noticed that no substantial obstaclc is interposed between the wagon-bed and the bolster beneath. The wagon-bed therefore can be hung quite low down, even when elastically supported.

I claim 1.. The combination of the bolster, the standards, the wagon-bed, the arms shaped and at.- tached to the bolster, as described, the bands, the springs, and the straps, substantially as described.

2. The combination of the bolster, the stand- 5 ards, the wagon-bed, the arms, the bands, the springs, and the straps, substantially as described.

23. The combination of the bolster, the standards, the Wagon-bed, the arms, the springs, and the straps, substantially as described.

4. The combination of the bolster, the Wagon-bed, the arms, the springs, and the straps, substantially as described.

The combination of the bolster, the arms E E, shaped and attached to the bolster at the central part thereof, as described, the standards, the Wagon-bed, the springs, and the straps, substantially as described.

6. The combination of the lmlster, the standards, the arms, and the band, substantially as described.
